Hello @LinceChacko and welcome to the ST Community.

What is the board that you are using, there is not any STM32 evaluation board based on the STM32WLE MCUs. The example SubGHz_Phy_PingPong is tested on the NUCLEO-WL55JC. So, it may require a few modification (i didn't tested personally).

Best Regards.

I am using the KG200Z module from Quectel. The module uses the STM32WLE5JC wireless controller from stm. it would be helpful if anyone provide the basic steps for configuring the Subghz phy and transmitting data.

Hello @LinceChacko 

For your Component, i think it will be a good idea to contact the Forum of the manufacturer of this component (available here). Also, you can have a look at this guide and adapt it to your MCU (not ST official and not tested by ST).

Best Regards.
